NAME

File::Find::Rule::BOM - Common rules for searching for BOM in files.

SYNOPSIS

use File::Find::Rule;
use File::Find::Rule::BOM;

my @files = File::Find::Rule->bom->in($dir);
my @files = File::Find::Rule->bom_utf8->in($dir);
my @files = File::Find::Rule->bom_utf16->in($dir);
my @files = File::Find::Rule->bom_utf32->in($dir);

DESCRIPTION

This Perl module contains File::Find::Rule rules for detecting Byte Order Mark in files.

BOM (Byte Order Mark) is a particular usage of the special Unicode character, U+FEFF BYTE ORDER MARK, whose appearance as a magic number at the start of a text stream can signal several things to a program reading the text.

See Byte order mark on Wikipedia.

SUBROUTINES

bom

my @files = File::Find::Rule->bom->in($dir);

The bom() rule detect files with BOM.

bom_utf8

my @files = File::Find::Rule->bom_utf8->in($dir);

The bom_utf8() rule detect files with UTf-8 BOM.

bom_utf16

my @files = File::Find::Rule->bom_utf16->in($dir);

The bom_utf16() rule detect files with UTF-16 BOM.

bom_utf32

my @files = File::Find::Rule->bom_utf32->in($dir);

The bom_utf32() rule detect files with UTF-32 BOM.

EXAMPLE1

use strict;
use warnings;

use File::Find::Rule;
use File::Find::Rule::BOM;

# Arguments.
if (@ARGV < 1) {
        print STDERR "Usage: $0 dir\n";
        exit 1;
}
my $dir = $ARGV[0];

# Print all files with BOM in directory.
foreach my $file (File::Find::Rule->bom->in($dir)) {
        print "$file\n";
}

# Output like:
# Usage: qr{[\w\/]+} dir

EXAMPLE2

use strict;
use warnings;

use File::Find::Rule;
use File::Find::Rule::BOM;

# Arguments.
if (@ARGV < 1) {
        print STDERR "Usage: $0 dir\n";
        exit 1;
}
my $dir = $ARGV[0];

# Print all files with UTF-8 BOM in directory.
foreach my $file (File::Find::Rule->bom_utf8->in($dir)) {
        print "$file\n";
}

# Output like:
# Usage: qr{[\w\/]+} dir

EXAMPLE3

use strict;
use warnings;

use File::Find::Rule;
use File::Find::Rule::BOM;

# Arguments.
if (@ARGV < 1) {
        print STDERR "Usage: $0 dir\n";
        exit 1;
}
my $dir = $ARGV[0];

# Print all files with UTF-16 BOM in directory.
foreach my $file (File::Find::Rule->bom_utf16->in($dir)) {
        print "$file\n";
}

# Output like:
# Usage: qr{[\w\/]+} dir

EXAMPLE4

use strict;
use warnings;

use File::Find::Rule;
use File::Find::Rule::BOM;

# Arguments.
if (@ARGV < 1) {
        print STDERR "Usage: $0 dir\n";
        exit 1;
}
my $dir = $ARGV[0];

# Print all files with UTF-32 BOM in directory.
foreach my $file (File::Find::Rule->bom_utf32->in($dir)) {
        print "$file\n";
}

# Output like:
# Usage: qr{[\w\/]+} dir
